No, fathers aren't better parents.

It would be silly to say that fathers are better parents, but it would also be silly to say that mothers are better parents. To say either one of those would be making a broad assertion about a whole group of people. In the life of any specific child, they could have a better father, a better mother or neither at all. Both men and women can be great parents.

Individuals are better or worse parents.

Generalizations like this aren't good for kids. Some fathers are amazing parents, just like some mothers are also amazing. But in each group there are a significant number who simply aren't cut out out for the job. But as gender biased as it sounds, I do think that daughters relate better to moms and that dads are more effective at parenting sons.
